How do I change font/colour in HTML?

You can use the font-family and the color attributes in your css file or <style> tag

You can go to the CSS file and put:
h2, h1 {
color: whatever color;
}

You can also do a easier version which is <font color"color">Text Here

I know something that can help you. I have been using an application with all kinds of fonts of different sizes and different designs for a long time. However, it is much more convenient when you want to distinguish your work somehow and choose something more unique. It is always more pleasant to read something enjoyable to the eye. To be honest, I like the most Nike font because it gives a richer look and I found about it on https://upfonts.com/nike-font.
